The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Na2SO4, or 142.04214 grams. Note that rounding errors may occur, so always check the results.
How many grams of Na2SO4 are in a mole?
Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).
How do you convert 1 mole to grams?
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
How many moles are in 4.5 grams of Na2SO4?
Explanation: If 4.5⋅L of a 3.0⋅mol⋅L−1 solution are required, this is a molar quantity of 4.5⋅L×3.0⋅mol⋅L−1=13.5⋅mol .
How many molecules are there in 450g of Na2SO4?
Divide 450 grams by the molecular mass, 142. You’ll get approximately 3.16 moles of Na2SO4 in 450 grams. Now you multiply that with 855.124*10^23 to get 2702.19*10^23molecules.
What is the mass of 1 mole of ch4?

What is the molar mass of ch3cooh?
∴ The mass of 10 moles of sodium sulphite = 1260 grams.
How many moles are in 450 grams of Na2SO4?
450 Na soullnol Na2SO4 16.02×1023 molec, Na₂SO4 = 119×1024 | 142.05g Na25041 Imol Naz Soy lec Na.
How do you find the molar mass of Na2SO4?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How many grams are in 5 moles?
Therefore, 160 g of oxygen is present in 5 moles.
How many grams are in 1 mole of oxygen?
Moles of a Substance and the Molecular Weight
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
